Lösung

\frac{d}{d x} (\frac{cot ( x )}{e ^{x}})

- \frac{csc ^{2} ( x ) + cot ( x )}{e ^{x}}

Schritte zur Lösung

\frac{d}{d x} (\frac{cot ( x )}{e ^{x}})

Wende die Quotientenregel an:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( cot ( x ) ) e ^{x} - \frac{d}{d x} ( e ^{x} ) cot ( x )}{( e ^{x} ) ^{2}}

\frac{d}{d x} (cot (x)) = - csc^{2} (x)

\frac{d}{d x} (e^{x}) = e^{x}

= \frac{( - csc ^{2} ( x ) ) e ^{x} - e ^{x} cot ( x )}{( e ^{x} ) ^{2}}

Vereinfache

\frac{( - csc ^{2} ( x ) ) e ^{x} - e ^{x} cot ( x )}{( e ^{x} ) ^{2}} : - \frac{csc ^{2} ( x ) + cot ( x )}{e ^{x}}

= - \frac{csc ^{2} ( x ) + cot ( x )}{e ^{x}}
